In anime, you often see someone getting their head chopped off by a single dagger strike. I can’t believe that’s feasible for a ‘normal’ human, but we also know that a guillotine will do the job handily, when the body is fixed in place.
So can a person with let’s say a sharp bastard sword cut off the head of a standing person?
This would be a full chop, not a slice. So you need momentum to overcome the tissue resistance and bone resistance. The heavier the sword the better for a full chop I think
